Use an alias in Route 53 for the apex. See: https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-to-cloudfront-distribution.html

You mean I have to create A records to IP4 and IP6? Does this defeat the purpose of having dynamic IP addresses to the various regions?
Alias records are route53-specific extensions to DNS functionality. They are not the same as A records. You can find more information here: https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resource-record-sets-choosing-alias-non-alias.html
You cannot use a CNAME for the zone apex. Alias records provide you similar functionality to CNAME records when used with CloudFront distributions, plus they can be used for the zone apex. If you create any alternate domain names though, eg. www.example.com, you should use a CNAME record.
